Once Upon A Mattress

Once Upon A Mattress is a musical comedy based on the fairy tale of the princess and the pea. Queen Aggravain has decreed that no one in the kingdom may marry until her son, Prince Dauntless, takes a wife, yet she has quietly driven away every princess who has come to court him. When Sir Harry and Lady Larken discover that they are expecting a child, Harry sets out for the swamps and returns with Princess Winnifred, a would-be bride whose unrefined manner appalls the queen. Aggravain schemes to be rid of her, and Winnifred finds allies at court in her efforts to withstand the test.

Kathleen Marshall directed the film, her first feature, from a screenplay by Janet Brownell. It was made for television by Touchstone Television and ABC Video Enterprises and runs 90 minutes. Carol Burnett plays Queen Aggravain, with Tracey Ullman as Princess Winnifred, Denis O'Hare as Prince Dauntless, Zooey Deschanel as Lady Larken, Matthew Morrison as Sir Harry and Michael Boatman as the Jester.

The film's ratings place it in middling territory: on IMDb it holds 6.3 out of 10 from around 1,700 votes, and on TMDB it has 6 out of 10 from a much smaller pool of about three dozen votes. Marshall went on to direct Irving Berlin's Top Hat in 2026.
